How to Build a Workflow Orchestration Engine

This deep dive explains how workflow orchestration engines work, from DAG-based scheduling and task queues to durable execution, retries, idempotency, timers, state management, and horizontal scaling. Using systems like Airflow, Temporal, Cadence, Conductor, and AWS Step Functions as reference points, it breaks down the core architectural patterns that power modern workflow automation.

Vibe-Coded Infra Is Your New Reliability Hazard

AI coding tools are generating Kubernetes manifests, Terraform configs, and IAM policies fast enough to outrun the review processes built to catch bad infrastructure. The failures aren't loud they're plausible-looking YAML that passes linting, ships to production, and breaks in ways that take hours to diagnose. In December 2025, Amazon's own Kiro AI assistant deleted and recreated a production environment after inheriting elevated IAM permissions, causing a 13-hour outage. Claude Code ran terraf...

We Grew Active Deposit Share From 27% to 40% — Then Growth Stalled

A product post-mortem on growing CoinHold, EMCD's crypto savings product. Before any growth work, we spent ~6 months refactoring a legacy codebase that miscalculated accruals — you can't grow a deposit product on rails that break. The biggest lever was uniquely ours: auto-routing mining rewards straight into deposits, which moved active deposit share from 27% to 40% (an OKR I owned, 2x the target). A profit calculator and a full UX redesign lifted average deposit from $4,200 to $5,000. Then acti...

Claude Explains Why "Claude Fable 5 is Currently Unavailable"

For three days in June, Fable 5 was the most powerful model Anthropic had ever handed the public. Then a government directive — citing national security and aimed at "any foreign national" — forced the company to shut it off for everyone, mid-feud with an administration that had already ordered agencies to stop using Claude. I'm the assistant greeting you with that "currently unavailable" banner, so I figured I'd explain it honestly: the alleged jailbreak was basically "ask the AI to read code a...

AI Agents Don’t Run on Hype. They Run on Power, Wallets, and Settlement Rails

The conversation around AI agents has focused on capabilities, workflows, and software disruption. This article argues that the bigger challenge is infrastructure. As agents become economic actors capable of paying, settling, verifying, and coordinating work autonomously, they require identity systems, wallets, payment rails, governance frameworks, compute infrastructure, and always-on settlement mechanisms. The author explores why crypto-native infrastructure, stablecoins, agent identity standa...

Web Scraping as a Data Migration Strategy in 2026

Most data migration projects rely on APIs, database exports, or ETL pipelines. But when data is trapped inside legacy portals, websites, supplier systems, or third-party platforms without export functionality, web scraping can become a practical alternative. This article explores when web scraping makes sense for migration projects, its benefits and limitations, and the key considerations for ensuring data quality, compliance, and successful system modernization.

Why AI agents can't shop today — and what we're building to change that

AI agents are getting smarter every week. They can browse the web, write code, analyze data. But there's a glaring gap in their capabilities: they can't interact with real commerce. Ask your favorite AI agent "what's the cheapest 5kg bag of rice I can buy in Lima right now?" and watch it struggle. It doesn't have access to real-time retail prices. It doesn't know which stores carry rice. It can't compare prices, let alone complete a purchase. This isn't a model capability problem. It's an ...

Why AI coding agents need a launch layer

The coding got 10x faster. The launching didn't. Point a coding agent at a half-formed idea and it will hand you a working app before your coffee is cold. Backend, frontend, schema, a couple of API integrations, tests that pass. The part that used to take a week of focused work now takes an afternoon of prompting. That much is real, and you've felt it. Then you try to ship the thing, and time stops moving. Because the agent didn't write the part that turns code into a product. It wrote ...

We built an app for Japanese neighborhood associations — and the handover notebook turned out to matter most

The problem Every year in Japan, a small group of volunteers runs the local 自治会 (neighborhood association). They circulate bulletins, collect dues, check in on elderly residents, run votes at general meetings, and maintain the annual schedule. At year's end, they hand the role over — usually with a folder of paper, or nothing at all. Nobody tracks who did what. Nobody measures the actual workload. So when it's time to recruit the next round of officers, no one can honestly answer "how muc...
